The Met Office has issued a forecast indicating that rain and thunderstorms could interrupt the United Kingdom's third heatwave of 2026, with scorching highs of 32 degrees Celsius set to grip parts of the country this week. Much of England and Wales are expected to remain sweltering over the coming days, with temperatures climbing between 30C and 32C as the hot spell continues.
Isolated Thunderstorms Expected in Southern England
While some showers and thunderstorms could hit isolated parts of southern England this week, many people will not see any rain and multiple areas will welcome large amounts of sunshine, according to the Met Office. Deputy Chief Forecaster Steven Keates explained: "The overall pattern continues to remain settled with large amounts of sunshine though this week, and temperatures peaking around 30C-32C across parts of England and Wales. In terms of rain, there's a chance of some showers and thunderstorms in isolated spots in the south of England on Wednesday and Thursday, but these are likely to be sporadic in nature, and many people won't see any rain this week."
Cooler Conditions on Eastern Coastlines
It will not feel quite as hot along eastern coastlines, where cloud and cooling onshore breezes are expected to keep temperatures lower than in inland parts of the country, the forecaster added. Looking ahead to the weekend, high pressure is forecast to re-appear from the northwest, pushing the risk of showers away and allowing settled, dry and warm conditions to return. While temperatures are expected to dip slightly from the peak reached during the middle of the week, much of the UK is still likely to enjoy fine and warm weather into Saturday.
Wildfire Risk and Water Safety Warnings
The Met Office has also warned of an increased risk of wildfires across parts of England and Wales as the prolonged spell of hot, dry weather continues. Stronger breezes in some southern areas could also create dangerous conditions for those heading into the water. A spokesperson for the National Fire Chiefs Council stated: "When the weather stays hot and dry, it only takes one spark to start a wildfire. What can begin as a small fire can spread incredibly quickly, putting people, homes, wildlife and our countryside at risk." Lee Pooley, Head of Safety at Paddle UK, warned that offshore winds can quickly carry paddleboarders and other water users away from the shore. Coastal winds can also blow water users out to sea faster than they may be able to paddle back. The Met Office and Paddle UK have urged people to check the forecast before heading into the water this week.
